Hi, We are trying to track down an issue when using the Frickin PPTP proxy. When we use "scrub in all random-id fragment reassemble" the GRE traffic fails to get rdr'd properly. If we remove the scrub directive the traffic flows as it should. Here is a look at the state list both ways: With scrub: self gre 192.168.10.198 <- 192.168.10.1 MULTIPLE:MULTIPLE self gre 192.168.1.199 -> 192.168.10.1 SINGLE:NO_TRAFFIC self gre 192.168.10.1 -> 192.168.1.199 MULTIPLE:MULTIPLE Without scrub: self gre 127.0.0.1 <- 192.168.10.1 <- 192.168.1.199 NO_TRAFFIC:SINGLE Also, why is the IP address changing in these states? We are only using .199 here as a test. Anyone have an idea? This works okay on OpenBSD 3.6. I am told by the Frickin PPTP author that it works ok on 6.0 but it appears broken on 6.2. FreeBSD pfsense.local 6.2-RELEASE FreeBSD 6.2-RELEASE #0: Fri Jan 12 15:32:48 EST 2007 sullrich@default.domain.com:/usr/obj.pfSense/usr/src/sys/pfSense.6 i386 Thanks in advance!
